, T0 aZZ whom it may concern:

Be it known that LMAXMORITZ J AENNIGEN, a citizen of Germany, and a resident of Vienna, in the Empire of Austria-Hungary, have in- Vented. certain new and useful Improvements in Apparatus for Spraying or Diifusing Fluids and Moistening Air in Workshops or other Places and for Like Purposes, of which the following is a specification.

This invention relates to an apparatus for spraying or diffusing fluids and moistening air in workshops and other places and for like purposes; and it consists in the construction and arrangement of the suction-casing combined. with the atomizer and diffuser arranged inside the said casing. The casing is so arranged that the water which is not atomized as well as the larger particles of water are discharged from the interior wall of the casing to outside the said casing closely beneath that part of the interior of the casing with which the water discharged by the atomizer is brought into contact, so that any large particles of water are prevented from passing down the interior of the casing in such a manner as to absorb considerable quantities of the properly-atomized water, and these large particles of water, as well as that which is not atomized, are caused to pass to the outside and immediately beneath that part of the interior of the casing whereonto the water is forced, so as to immediately be taken out of contact with the air-current and properly-atomized water traversing the interior of the casing. The said casing therefore difiers materially from casings hitherto used, in which the water not atomized or properly atomized is only discharged just above the catch-tank, whereby not only is a considerable portion of the properly-atomized water reabsorbed and carried away with the said unatomized water or improperly atomized water, but water which is not properly atomized is conveyed into the atmosphere to be moistened.

In order that the water which is not atomized and the larger particles of water shall be deflected and discharged immediately beneath the place where the liquid from the atomizer is forced into contact with the inside of the casing, the said casing is interrupted or has slots or openings all around immediately beneath the part with which the water from the atomizer comes in contact, which can be done by making the casing in two or more parts, a free annular space being left between them and they being arranged underneath one another or the one partly inserted into the other, so that the upper part overlaps the inner part.

In the accompanying drawings I have illustrated in Figures 1, 2, and 3 in vertical section, as examples, three constructions of casings according to my invention. Figs. 4., 5,

6, 7, 8, and 10 are central vertical sections of diiferent forms of my atomizing or diffusing device, and Fig. 9 is a similar view of several different forms of tips.

The casing consists of the upper portion G, inclosing the atomizer and difiuser Z. In the arrangement Fig. 1 this portion Gis widened out just below the place where the liquid strikes the interior of the casing, this widened portion extending down outside the upper part of the second portion G of the casing, the upper edge or rim of which second por tion extends to near the inner outwardly-extending side of the portion G, so as to leave a free space between both portions of the casing for the deflection and discharge of the water not atomized or not properly atomized. The portion G may either have its lower edge also widened out similarly to the part G and receive an analogous portion G and this latter another portion, if desired, and so on, or the said portion G may, as represented in Fig.3, extend down to the catch-tank F.

In the arrangement shown in Fig. 2 the portions G G G G constituting the casing, are in the form of truncated cones and are so inserted into one another that the respective edges overlap each other, as shown, annular free spaces being left between eachadjaceut two of them.

The constituent portions of thecasing may be simply cylindrical or of any other suitable shape. nearest to the catch-tank F is turned upward, so as to form a catch groove or channel for the deposited water, from which channel the The edge or rim of the portion lying IOO water overflows or passes by any suitable channelinto the catch-tank or into thereturnconduit.

The space inside the casing is of the same vcross-sectional area throughout in the arrangement Fig. l and gradually decreases in the arrangement Fig. 2.

- case the speed of the induced air-current remains uniform, while in the latter case the said current increases in proportion as the.

space lessens. If, however, the closely-adjacent edges of the portions G and G be first turned outward and then inward, as shown in Fig. 3, the induced air-currents will first expand in the wider part and subsequently be compressed in the narrower part, whereby a very eificient flow and supply of air is attained. V C V I- V In all cases the water not atomized .as .well as the large particles of water are discharged to the outside of the casing immediately beneath the part of the interior of the casing whereonto the water from, the atomizer isjet w impinges in a straight line at a pressurewhich is in accordance with the purposes for which the device .is intended- The central. core" w? of the liquid-jet w (thesaid core being. shown by'a solid black line) penetrates the, bottle-shaped body A, which is filled with.

water up to its mou th m 'and the water which enters body A loses its ms viva and displaces 1 an equal quantity of water from the vessel A,

which steadily and evenly leaves the bottlemouth m over theedge it without forming a vortex and without any concussion joinst'h'e liquid veil or spray O and is atomized. The liquid veil or spray C is formed at the edgek of the bottle -.mouth by the outer-jet w im-,

pinging against the edge of the mouth m.

According as either a plate shaped liquid spray or Veil G or liquid cone C, respectively, or an upwardly or downwardly directed spray or cone is required the edge of the mouth m' is either flattened out broadly, as shown in-. Fig. 5, or is formed conically inward, as I shown in Fig. 6, or is formed conicallyoutwardor slightly flattened, as shown in Fig. 4;. In all cases, however, the liquid veil or spray O is formed directly on the mouth edgeof the hollow body A, while the central stream or water is completely separated from the exterior layer or mantle of the jet of water. forming the veil or cone -O,'on which the at-L, omizing and dilfusing eifec't takes place, so

that consequently the said core is not, as in In the former the caseof simple solid or slightly cut-out r'e'- coil bodies or counter-current nozzles,.(against which the jet is caused to impinge,) forced back upwardly. This atomizingefiect takes place equally around the circular line of the mouth edge and is therefore extremely uniform and complete. I To further facilitate a steady and uniform outflow of the displaced water from the body A, there can be arranged .axi'ally in the interior of the hollow body A a in-s' terminatin in a point Fig. 5, or

small tube 1", open at its bottom, Fig; 6,

upon which point, Fig. 5, the water is forced,

and the'reb'y'rapidlyspread out ordivided, or. "into which tubethewater enters and disperses itself therein, Fig. 6, while in both cases any too-strong concussion of the water accumulated inthe-interior of the hollow body is prevented.

i The hollow boaitshapta body-A b a... rangement such as is shown in Fig. 7 -ofiers a simple means for multiplying the liquidveil O to any extent by'providing the: bottom I) of the bottle with a bore m2, .coaxialwith the mouth m and .ofa diameter in accordance with the thickness 'oi the liquid spray tobe produced. The liquid corew within the bottle-shaped part V, for instance has solely to overcome the resistance offered by theliquid itself if the bore m be equal to-or larger than m, Fig. 7; and in this case-the second liquid-spray Obeco mes stronger than would be the case if m were smaller-than 'm'.

Accordingto the purposeassigned to the nozzle the'above-described multiplication of the liquid-sprays may beelfected any number-bf times, while on the other hand the nozzle mayreceive any other appropriate construction.

Speakinggenerally, b'y-insertingn multipliers- V 'n +1 sprays or veils of liquid will result.

The total amount of water of all the n+1 sprays of liquid is equal to the amount of -liq uid supplied from the primary nozzle 'm, Fig.

merely serve-to split off a second, third, and soon spray of waterand may, therefore, simply take the form of a body with cylindrical orcon'ical bore, Fig. 9, is that the water is more perfectly atomized, for each of the sev- 'eral separate Water-sprays has-its own atomizing eflfect.

Fig. 1 Orepresents the'combination-of two single-jet nozzles acting with their respective months 10 and w againstone duplex bottleshaped body A A ,con1mon to each. I do'n'ot consider the diaphragm Sessential in such double-nozzleapparatus.

Although for the purpose of descri-ptionl have referred to water, it will be understood that any other fluid to the spraying or diffusing of which the apparatus is applicable can be used in placeof water. r 1 1 I TI-Iaving now particularly described and as certained the nature of the said invention and IIdeclare that what I claim isl 1.
